Abstract
A low-profile intercranial device including a low-profile static cranial implant and a functional neurosurgical implant. The low-profile static cranial implant and the functional neurosurgical implant are virtually designed and interdigitated prior to physical assembly of the low-profile intercranial device.
Claims17
An intercranial device, comprising:
- a static cranial implant shaped and dimensioned for placement within an intercranial space defined by a resected portion of a patient's skull, the static cranial implant including an outer convex first surface and an inner concave second surface, the static cranial implant including:
- a base member with an outer convex first surface, an inner concave second surface, and a peripheral edge extending between the outer convex first surface and the inner concave second surface and defining a thickness between the outer convex first surface of the base member and the inner concave second surface of the base member, the peripheral edge being tapered to conform to a resected portion of the patient's skull upon implantation, the base member defining a recess formed in the outer convex first surface thereof, the recess having side walls and a bottom, the recess being shaped and dimensioned to receive a functional neurosurgical implant;
- and
- a cover cranial implant member shaped and dimensioned for selective placement over the recess to define a cavity in which the functional neurosurgical implant may be positioned, the cover cranial implant member includes an outer convex first surface, an inner concave second surface, and a peripheral edge shaped and dimensioned for engagement with the outer convex first surface of the base member along a periphery of the recess of the base member.

An intercranial device, comprising:
- a static cranial implant shaped and dimensioned for placement within an intercranial space defined by a resected portion of a patient's skull, the static cranial implant including:
- a base member with an outer surface, an inner surface, a thickness defined between the outer and inner surfaces, and a peripheral edge shaped and dimensioned to conform to a resected portion of the patient's skull upon implantation, the base member defining a recess formed in the outer surface thereof, the recess having side walls and a bottom, the recess being shaped and dimensioned to receive a functional neurosurgical implant;
- and
- a cover cranial implant member shaped and dimensioned for selective placement over the recess to define a cavity in which the functional neurosurgical implant may be positioned:
- wherein the static cranial implant includes alignment markings and the alignment markings are in the shape of a cross or the alignment markings include a first alignment marking formed upon the static cranial implant so as to identify a superior to inferior direction of the static cranial implant when properly implanted and a second alignment marking formed upon the static cranial implant so as to identify a posterior to anterior direction of the static cranial implant when properly implanted.

- a base member with an outer surface, an inner surface, a thickness defined between the outer and inner surfaces, and a peripheral edge shaped and dimensioned to conform to a resected portion of the patient's skull upon implantation, the base member defining a recess formed in the outer surface thereof, the recess having side walls and a bottom, the recess being shaped and dimensioned to receive a functional neurosurgical implant;
- and
- a cover cranial implant member shaped and dimensioned for selective placement over the recess to define a cavity in which the functional neurosurgical implant may be positioned:
- wherein the static cranial implant includes laser cut lines identifying potential cuts for the intercranial device or the static cranial implant includes laser markings to provide an indication of critical anatomy relating to installation of the intercranial device.

An intercranial device, comprising:
- a static cranial implant shaped and dimensioned for placement within an intercranial space defined by a resected portion of a patient's skull, the static cranial implant including an outer convex first surface and an inner second surface, the static cranial implant including:
- a base member with an outer convex first surface, an inner second surface, and a peripheral edge extending between the outer convex first surface and the inner second surface and defining a thickness between the outer convex first surface of the base member and the inner second surface of the base member, the peripheral edge being shaped and dimensioned to conform to a resected portion of the patient's skull upon implantation, the base member defining a recess formed in the outer convex first surface thereof, the recess having side walls and a bottom, the recess being shaped and dimensioned to receive a functional neurosurgical implant;
- and
- a cover cranial implant member shaped and dimensioned for selective placement over the recess to define an enclosed cavity in which the functional neurosurgical implant may be positioned, the cover cranial implant member includes an outer first surface, an inner second surface, and a peripheral edge shaped and dimensioned for engagement with the outer convex first surface of the base member along a periphery of the recess of the base member such that the base member and the cover member, when implanted, together define an exterior shape of the static cranial implant that conforms with a contour of the patient's skull and minimizes abnormal shapes, visible contours, and/or craniofacial deformities.
